Douglas Fir - Seeds

Pseudotsuga menziesii is an evergreen conifer native to North America that can grow over 60 m tall in natural forests. Despite its common names, it is neither a true fir nor a pine but belongs to its own genus, Pseudotsuga.

Its needles are soft, dark green, and release a pleasant resinous scent when crushed. The tree produces distinctive hanging cones with protruding bracts that resemble small tongues. It is widely cultivated in forestry due to its strong, valuable timber and is also planted as an ornamental tree in parks and large gardens.

It prefers deep, moist, well-drained soils and grows best in full sun or partial shade. Douglas fir is cold-hardy and can live for several centuries.

How to sow Pseudotsuga menziesii seeds

Seeds germinate best after cold stratification. Place them in slightly moist sand or vermiculite in the refrigerator at about 4 °C for 4–6 weeks. After stratification, sow the seeds in trays with light, well-drained soil and cover them lightly. Keep the substrate moist but not waterlogged and place the trays in a bright location. Germination usually occurs within 2–4 weeks.
